terminal velocity

Question 1

When does air resistance increase?

Answer 1

with speed

Question 2

What is Newtons first law?

Answer 2

states that an object will remain at rest or move with a constant speed in a
straight line (constant velocity) unless acted upon by an unbalanced force.

Question 3

What is Newtons second law?

Answer 3

F un = m a

Question 4

What is Newtons third law?

Answer 4

states that for every action (force) there is an equal and opposite reaction
(force). Two objects - swap their names: the force of the foot on the ball is equal and opposite to
the force of the ball on the foot.

Question 5

What is the weight of an object in freefall?

Answer 5

constant

Question 6

What eventually balances weight in freefall?

Answer 6

air resistance

Question 7

What does air weight balancing cause?

Answer 7

terminal velocity to be reached

Question 8

What is terminal velocity?

Answer 8

steady speed achieved by an object freely falling

Question 9

What happens when an object reaches terminal velocity?

Answer 9

the speed of a moving object is no longer increasing or decreasing
the object’s acceleration (or deceleration) is zero
the total force on the object is zero
